Opinions, satisfaction and expectations of individuals with multiple sclerosis about telerehabilitation services.

OBJECTIVE: The opinions, satisfaction, and expectations of telemedicine can provide essential data for remote health services in individuals with Multiple Sclerosis (MS). The study aimed to demonstrate the views (barriers-benefits), satisfaction, and expectations of individuals with MS about telerehabilitation services. METHODS: A prospective cross-sectional was conducted with 82 individuals with MS who received telerehabilitation services for at least one year. The participants have completed SymptoMScreen, Beck Depression Inventory (BDI), Telehealth Usability Questionnaire (TUQ), Telemedicine Satisfaction Questionnaire (TSQ), Telehealth Barriers Questionnaire (TBaQ and Telehealth Benefits Questionnaire (TBeQ). RESULTS: As the age of individuals with MS increased, TUQ (r: -0.517, p < 0.001) and TBeQ (r: -0.383, p < 0.001) decreased, while TSQ (r: 0.405, p < 0.001) and TBaQ (r: 0.390, p < 0.001) increased. SymptoMScreen score (r: -0.288, p < 0.05) was weakly associated with TUQ. In addition, TUQ, TSQ, TBeQ, and TBaQ were strongly correlated (p < 0.001). CONCLUSION: In order to improve usability and satisfaction in telerehabilitation services, the age, symptom severity, and education levels of individuals with MS should be considered. Telehealth methods with high usability should be preferred to increase patient satisfaction.

Psychosocial Effects of the Pandemic on MS Patients at a University Hospital Following Patients with Telemedicine, Cross-sectional Study.

Introduction: The psychosocial effect of the pandemic on people with a disease such as multiple sclerosis (MS) that can cause disability and which medications that affect the immune system are used in treatment should be evaluated by physicians. We aimed to determine the psychosocial effects of the pandemic on MS patients and to evaluate the working and treatment continuation status, compliance with pandemic rules, and their perceptions regarding coronavirus disease 2019 (COVID-19). Methods: This study was designed as a cross-sectional and descriptive survey study. A total of 315 MS patients' demographic data, comorbidities, and degrees of disability, Beck Depression Inventory (BDI), Coronavirus Anxiety Scale (CAS), and compliance scores with pandemic restrictions were evaluated. Results: In the first period of the pandemic, approximately one-third of the patients were found to have major depression, and approximately 10% to have COVID anxiety. Both COVID anxiety and BDI scores were significantly higher in patients with symptoms suggestive of an attack during the pandemic process (p:0.0001 and p:0.002). CAS was higher in those who had a COVID-19 contact (p:0.045). BDI scores were significantly higher (respectively p:0.034, p:0.006, p:0.0001) in married/cohabiting patients, in patients who went on unpaid leave or lost their job, and in patients who described worsening of their previous MS-related complaints. Conclusion: Although the pandemic negatively affects the psychosocial status of MS patients, this effect can be reduced by identifying the groups that may be affected via telemedicine and taking necessary interventions.

Retrospective analysis of effectiveness of fingolimod in real life setting in Turkey (REFINE).

BACKGROUND: During multiple sclerosis (MS) treatment different modes of action such as lateral (interferon beta to glatiramer acetate or glatiramer acetate to interferon beta) or vertical (interferon beta/glatiramer acetate to fingolimod) drug switch can be performed. This study aims to investigate the clinical effectiveness of switching from the first-line injectable disease modifying treatments (iDMTs) to fingolimod (FNG) compared to switching between first-line iDMTs. METHODS: This is a multicenter, observational and retrospective study of patients with relapsing-remitting MS who had lateral and vertical switch. The observation period included three key assessment time points (before the switch, at switch, and after the switch). Data were collected from the MS patients' database by neurologists between January 2018 and June 2019. The longest follow-up period of the patients was determined as 24 months after the switch. RESULTS: In 462 MS patients that were included in the study, both treatments significantly decreased the number of relapses during the postswitch 12 months versus preswitch one year while patients in the FNG group experienced significantly fewer relapses compared to iDMT cohort in the postswitch 12 months period. FNG cohort experienced fewer relapses than in the iDMT cohort within the postswitch 2 year. The mean time to first relapse after the switch was significantly longer in the FNG group. DISCUSSION: The present study revealed superior effectiveness of vertical switch over lateral switch regarding the improvement in relapse outcomes. Patients in the FNG cohort experienced sustainably fewer relapses during the follow-up period after the switch compared the iDMT cohort. Importantly, switching to FNG was more effective in delaying time to first relapse when compared with iDMTs.

Effects of comorbid diseases on clinical outcomes in patients with myasthenia gravis.

BACKGROUND: This cross-sectional study was undertaken to evaluate the existence and distribution of comorbid disorders among myasthenia gravis (MG) patients according to subgroups and to identify the effects of the comorbid diseases of MG patients on clinical outcomes. METHODS: The patients were divided into six subgroups according to serum antibodies, age at onset, and thymoma presence. All patients were treated in line with the International Consensus Guidance for Management of Myasthenia Gravis. To assess the clinical outcome after treatment for MG, we used the MGFA Post-intervention Status. In generalized MG patients, the good prognosis group included patients who were classified as having minimal-manifestation status or better. In ocular MG patients, the remission subgroup included patients who were classified as having complete stable remission or pharmacological remission status. RESULTS: Our study included 168 MG patients, 85 were female while 83 were male. Comorbid diseases were present in 124 (73.8%) MG cases. After at least 1 year of follow-up, 106 (86.8%) of the generalized MG patients were in the good prognosis group and 16 (13.2%) generalized MG patients were in the poor prognosis group. 27 (58.6%) ocular MG patients were in the remission group and 19 (41.3%) ocular MG patients were in the non-remission group. Hypertension increased the risk of poor prognosis by 3.55-fold among patients with generalized MG and type 2 DM increased the risk of not achieving remission by 9.32-fold among patients with ocular MG. CONCLUSION: Hypertension and type 2 DM had negative effects on the clinical outcomes of MG.

The relationship between severity of overactive bladder symptoms and cognitive dysfunction, anxiety and depression in female patients with multiple sclerosis: Running head: OAB-V8, BICAMS and HAD scale in MS.

BACKGROUND: Overactive bladder (OAB), cognitive dysfunction, depression and anxiety are common problems encountered in MS. This study was planned to investigate the relationship between the severity of OAB symptoms and cognitive function, anxiety and depression in MS. METHODS: 100 patients with MS diagnosis with OAB symptoms were recruited. OAB symptoms was assessed with the OAB-V8 questionnaire. Symbol Digit Modalites Test (SDMT), California Verbal Learning Test II (CVLT-II) and Brief Vasospatial Memory Test-Revised (BVMT-R) in BICAMS Battery were used to evaluate cognitive function. Depression and anxiety were assessed with the Hospital Anxiety Depression (HAD) Scale. RESULTS: The mean age of the patients was 40.9±12.3, the duration of the disease was 9.03±6.89 years, and the mean OAB-V8 score was 17.6±8.9. SDMT test (r=-0.299, p<0.01) showed a moderately significant, CVLT-II (r= -0.219, p<0.05) and BVMT-R (r=-0.218, p<0.05) tests showed a weakly significant negative correlation with OAB-V8 score. There was a moderate positive correlation between the OAB-V8 score and HAD-D (r=0.279, p=0.005) and HAD-A (r=0.318, p=0.001) scores. SDMT and BVMT-R scores were significantly lower in anticholinergic (Ach) drug users (especially oxybutynin users) compared to those who did not use Ach drugs. CONCLUSIONS: It has been observed that the severity of OAB symptoms is related to worsening of information processing speed and an increase in depression and anxiety. It has been determined that there is a significant effect on information processing speed, visual learning and memory in patients using Ach drugs, especially in those using oxybutynin, compared to those who do not use Ach drugs.

Reliability and Validity of the Turkish Version of the Multiple Sclerosis Knowledge Questionnaire.

Introduction: Multiple Sclerosis Knowledge Questionnaire (MSKQ) is a self-administered inventory assessing patients' knowledge about Multiple Sclerosis. In this study, we aimed to test the reliability and validity of MSKQ in Turkish patients. Methods: Patients with Multiple Sclerosis who attended an education seminar in our university hospital were enrolled in the study. Results: Fifty-eight patients completed and returned the questionnaire twice, before and after the seminar. Mean number of items that were answered correctly in the first round was 12.8 (5.2), which increased to 18.7 (3.2) in the second round after the seminar. This increase was found to be significant (p<0.01). Conclusion: Questions regarding general characteristics of the disease were found to be answered correctly more often than those questions regarding diagnostic and treatment options. This finding indicates that patients may be more interested in the general characteristics of the disease and in the factors that may have started the disease process. Higher number of incorrect answers regarding diagnostic and treatment strategies may be caused by a lack of interest on the part of the patient who may perceive these subjects to be too complex or who may choose to leave decision-making to healthcare professionals. Also, physicians may be unable to inform patients in these areas because of a lack of time or resources. New molecules developed for the treatment of Multiple Sclerosis makes it even more difficult for patients to follow and form their own opinions about the treatment process. These results show us that patient education is essential and our patients need more educational resources, especially regarding treatment options. The significant increase in the number of correct answers after the education seminar supports the need for broader patient education (p<0.01). Turkish version of MSKQ is a reliable and valid measure for assessing patients' level of knowledge.

The Turkish experience of COVID-19 infection in people with NMOSD and MOGAD: A milder course?

BACKGROUND: COVID-19 is a multisystemic infection with variables consequences depending on individual and comorbid conditions. The course and outcomes of COVID-19 during neuromyelitis optica spectrum disorders (NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disorders (MOGAD) are not clearly known. OBJECTIVE/METHODS: The aim of this study was to examine the features and outcomes of COVID-19 infection in NMOSD and MOGAD patients. The patients' demographic and clinical factors, disease modifying treatment (DMT) used and disease information of COVID-19 infection were recorded. Conditions leading to hospitalization and severe exposure to COVID-19 infection were also analyzed. RESULTS: The study included 63 patients from 25 centers. Thirty-two patients (50.8%) belong to AQP-4 seropositive group, 13 (20.6%) and 18 (28.6%) were in MOG-positive and double-seronegative groups, respectively. Risk factors for severe COVID-19 infection and hospitalization were advanced age, high disability level and the presence of comorbid disease. Disease severity was found to be high in double-seronegative NMOSD and low in MOGAD patients. No statistically significant effect of DMTs on disease severity and hospitalization was found. CONCLUSION: In NMOSD and MOGAD patients, advanced age, high disability and presence of comorbid disease pose risks for severe COVID-19 infection. There was no direct significant effect of DMTs for COVID-19 infection.

The reliability and validity of the Turkish version of the Telemedicine Satisfaction and Usefulness Questionnaire (TSUQ) and Telemedicine Patient Questionnaire (TPQ) in individuals with multiple sclerosis.

OBJECTIVE: The study was aimed to translate and adapt the Telemedicine Satisfaction and Usefulness Questionnaire (TSUQ) and Telemedicine Patient Questionnaire (TPQ) into Turkish, thereafter to analyze the psychometric properties of both questionnaires. METHODS: A total of 149 multiple sclerosis (MS) patients were recruited in the study. For 4 years, all patients were supervised by a department clinician using telemedicine. Cronbach's alpha coefficient was used to assess internal consistency. By evaluating the scores of 41 retested patients 1 week later, the test-retest reliability was determined using the intraclass correlation coefficient (ICC). Pearson's correlation coefficient was used to assess the construct validity (r). RESULTS: A total of 149 patients (103 women, 46 men) with a mean age of 40.9±10.9 years were included in the study. MS duration of the patients was 9.15±6.24 years. Internal consistency of all items and the total score of the TSUQ were excellent (>0.80; ranged 0.971-0.974). On the other hand, the internal consistency of all items and total score of the TPQ was excellent, either (>0.80; ranged 0.878-0.890). The ICC of the TSUQ's and TPQ's total score was excellent (>0.80). The correlation between TSUQ and TPQ was strong (r=0.734, p<0.01). In addition, there was moderate relationship between the TSUQ and the Beck Depression Scale (BDS) (r=-0.363, p<0.01). On the other hand, there was low correlation between TPQ and BDS (r=-0.217, p<0.05). CONCLUSION: The Turkish version of the TSUQ and the TPQ is valid and reliable in individuals with MS.

The comparison of fatigue, sleep quality, physical activity, quality of life, and psychological status in multiple sclerosis patients with or without COVID-19.

PURPOSE: The study was purposed to investigate the effect of COVID-19 disease on fatigue, sleep quality, physical activity, quality of life, and psychological status in people with MS. METHODS: A total of 104 people with MS, including 46 of them with COVID-19 disease history, were enrolled in the study. All patients were evaluated with the Expanded Disability Status Scale (EDSS), Fatigue Severity Scale (FSS), Pittsburgh Sleep Quality Index (PSQI), International Physical Activity Questionnaire Short Form (IPAQ-SF), the EuroQoL Instrument (EQ-5D-3L), the Fear of COVID-19 Scale (FCV-19S) and the Coronavirus Anxiety Scale (CAS). RESULTS: People with MS in the COVID-19 positive group had a significantly lower IPAQ-Total score (p = 0.014). Besides, the FCV-19S scores of COVID-19 positive patients were significantly higher (p = 0.006). EQ-5D-3L Index and EQ-5D-3L VAS scores were higher in the group with COVID-19 (p1 = 0.021, p2 = 0.014, respectively). FCV-19S had a moderate correlation with EDSS (r = -0.362). IPAQ-Total was moderately associated with MS duration, EDSS and FSS (r1 = -0.471, r2 = -0.389, r3 = -0.388, respectively). The EQ-5D-3L Index was moderately correlated with FSS (r1 = -0.404). There was a weakly significant relationship between EQ-5D-3L Index and BMI, MS duration, PSQI and CAS (r1 = -0.471, r2 =-0.389, r3 = -0.388, r4 = -0.326, respectively). On the other hand, EQ-5D-3L was moderately associated with VAS and EDSS and PSQI (r1 = -0.393, r2 = -0.357, respectively). CONCLUSION: COVID-19 negatively affected the people with MS's physical activity and coronavirus related fear parameters. However, the causality of this influence should be investigated in detail.

Retinal Nerve Fiber Layer Thickness Correlates with Serum and Cerebrospinal Fluid Neurofilament Levels and is Associated with Current Disability in Multiple Sclerosis.

INTRODUCTION: The main purpose of the present study is to confirm Peripapillary Retinal Nerve Fiber Layer (pRNFL) thickness is a biomarker of axonal degeneration in patients with Multiple Sclerosis (MS) and to evaluate its relationship with Neurofilament heavy chain (NfH) and Nitrotyrosine (NT). METHOD: We quantified serum (s) and/or cerebrospinal fluid (CSF) NfH and NT levels in 30 relapsing-remitting MS patients (RRMS), 16 secondary progressive MS (SPMS) patients and in 29 control subjects matched for age and gender. Optical coherence tomography (OCT) measurements of pRNFL were performed in all subjects. Clinical outcomes were tested by Multiple Sclerosis Functional Composite (MSFC) and Expanded Disability Status Scale (EDSS). RESULTS: RRMS patients exhibited significantly higher NfH/NT levels (99 pg/mL, 107.52 nM respectively) than controls (74 pg/mL, 48.72 nM) in CSF (p<0.0001), but not in sera. SPMS patients had significantly higher s NfH/NT values (111.25 pg/mL, 1251.77 nM respectively) and lower mean pRNFL thickness (79 µm) than patients with RRMS (98.50 µm) and controls (108 µm) (p<0.0001). pRNFL thickness was significantly correlated with all clinical disability measurements (EDSS, Trail Making test, 9-Hole Peg Test, and PASAT) in both RRMS and SPMS (p<0.001, p=0.02, p=0.03, p=0.02 respectively). A positive correlation was also found between serum and/or CSF NfH levels and EDSS scores in RRMS and SPMS (p<0.001, p=0.02 respectively). The pRNFL thickness was also correlated significantly with serum and/or CSF NfH levels but not with s/CSF NT levels in both clinical forms of MS (p<0.01, p<0.001 respectively). CONCLUSION: The current study demonstrated that both pRNFL and s/CSF NfH are reliable and quantitative biomarkers that correlate with current disease course and cross-sectional measure of disability in patients with MS.

Vestibular impairment in Charcot-Marie-Tooth disease.

OBJECTIVE: To find out if Charcot-Marie-Tooth (CMT) patients, who have peripheral vestibular as well as peripheral somatosensory impairment, have worse postural balance than those who do not. METHODS: We studied 32 patients with various CMT phenotypes and genotypes. Vestibular function was measured with the video head impulse test (vHIT) which tests vestibulo-ocular reflex (VOR) gain from each of the six semicircular canals in response to rapid head rotations. Postural balance was evaluated with a battery of four postural tests with emphasis on the modified clinical test of sensory integration in balance (mCTSIB). RESULTS: Half of the 32 patients had some impairment of vestibular function ranging from mild, affecting only 1-2 semicircular canals, to almost total affecting all 6 semicircular canals. Their mCTSIB scores correlated with VOR gain from the vertical rather than from the lateral semicircular canals. The worse the vertical VOR gain the worse the mCTSIB score. CONCLUSION: We propose that any CMT patient could have clinically inapparent vestibular impairment that can be easily measured with the vHIT. This vestibular impairment could be contributing to their imbalance and could respond to a focused vestibular rehabilitation program.

'Is RLS a harbinger and consequence of MS?: Striking results of the 'RELOMS-T' study'.

BACKGROUND: Although studies report a high prevalence rate of restless legs syndrome (RLS) among patients with multiple sclerosis (PwMS) ranging from 13.3 to 65.1%, little is known about the causes of this relationship. METHODS: To ascertain the prevalence, features and impact of RLS among PwMS a nation-wide, multicenter, prospective and a cross-sectional survey, designed to reflect all of the PwMS throughout Turkey, was conducted in 13 centers. Exploring the relationship of the two conditions could possibly contribute to the understanding of the causes of the high and wide-ranging prevalence rates and the pathophysiology of both diseases. RESULTS: Of the 1068 participants 173 (16,2%) found to have RLS [RLS(+)] and 895 (83,8%) did not [RLS(-)]. Among the RLS(+) 173, all but 8 patients (4,6%) were underdiagnosed in terms of RLS. More than half of the patients with RLS had 'severe' or 'very severe' RLS. The onset of RLS was before or synchronous with the onset of MS in about a half of our patients. CONCLUSION: We conclude that RLS should be meticulously investigated in PwMS and MS can be a direct cause of RLS at least in part of PwMS. Our data about the timing of the onset of MS and RLS, along with the high prevalence of RLS in PwMS suggest that the pathologic changes in the initial phases of MS can possibly trigger RLS symptoms.

Comparative analysis of fingolimod versus teriflunomide in relapsing-remitting multiple sclerosis.

BACKGROUND: Fingolimod and teriflunomide are commonly used in the treatment of relapsing-remitting multiple sclerosis (RRMS). These have not been compared in controlled trials, but only in observational studies, with inconclusive results. Comparison of their effect on relapse and disability in a real-world setting is therefore needed. OBJECTIVES: The objective of this study was to compare the efficacy of fingolimod and teriflunomide in reducing disease activity in RRMS. METHODS: This multicenter, retrospective observational study was carried out with prospectively collected data from 15 centers. All consecutive RRMS patients treated with teriflunomide or fingolimod were included. Data for relapses, Expanded Disability Status Scale (EDSS) scores and brain magnetic resonance imaging (MRI) scans were collected. Patients were matched using propensity scores. Annualized relapse rates (ARR), disability accumulation, percentage of patients with active MRI and treatment discontinuation over a median 2.5-year follow-up period were compared. RESULTS: Propensity score matching retained 349 out of 1388 patients in the fingolimod group and 349 out 678 in the teriflunomide group for final analyses. Mean ARR decreased markedly from baseline after 1 and 2 years of treatment in both the fingolimod (0.58-0.17 after 1 year and 0.11 after 2 years, p < 0.001) and teriflunomide (0.56-0.29 after 1 year and 0.31 after 2 years, p < 0.001) groups. Mean ARR was lower in fingolimod-treated patients than in those treated with teriflunomide at years 1 (p = 0.02) and 2 (p = 0.004). Compared to teriflunomide, the fingolimod group exhibited a higher percentage of relapse-free patients and a lower percentage of MRI-active patients after 2.5-year follow-up. Disability worsening was similar between the two groups. Patients were less likely to discontinue fingolimod than teriflunomide (p < 0.001). CONCLUSION: Fingolimod was associated with a better relapse control and lower discontinuation rate than teriflunomide. The two oral therapies exhibited similar effects on disability outcomes.

Silent Tumefactive Demyelinating Lesions and Radiologically Isolated Syndrome.

Demyelinating lesions larger than 2 cm in diameter, with or without edema, are known as tumefactive demyelinating lesions (TDLs). They constitute a rare inflammatory demyelinating disorder of the central nervous system. TDLs are typically characterized by headaches, cortical symptoms such as aphasia, hemiparesis, hemisensory deficits, seizures, and changes in consciousness. TDLs may occur in patients with or without an established diagnosis of MS or may occur as the initial demyelinating event. They may also be observed during follow-up in patients with MS, neuromyelitis optica, acute disseminated encephalomyelitis, or other autoimmune diseases. Differential diagnosis includes brain tumors, abscess, granulomatous diseases, and vasculitis. In some cases, it may be very difficult to distinguish TDLs from a tumor, such that biopsy might be needed. However, no cases of asymptomatic TDLs have yet been reported in the literature. Hence, in this report, we present a case involving an asymptomatic TDL detected incidentally during magnetic resonance imaging in an 18-year-old man. The patient did not develop any symptoms during the 1-year follow-up period. During follow-up, the patient was diagnosed with a radiologically isolated syndrome. TDLs have not previously been identified as radiologically isolated syndrome. Thus, reporting similar cases in the future will help in further understanding this phenomenon.

Vestibular impairment in chronic inflammatory demyelinating polyneuropathy.

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a common, treatable, autoimmune peripheral neuropathy considered to produce imbalance by weakness and proprioceptive impairment rather than vestibular impairment. We measured semicircular canal vestibular function in 21 CIDP patients (15M/6F) by the video head impulse test and postural stability with a battery comprising the modified Clinical Test of Sensory Integration and Balance, the Berg Balance Scale, the Dynamic Gait Index, the Fall Efficiency Scale, and the International Cooperative Ataxia Rating Scale. Of the 21 patients, 16 had vestibular impairment, ranging from mild-affecting just a single semicircular canal, to severe-affecting all 6 canals. Although the severity of the vestibular impairment did not correlate either with the severity of the postural imbalance or of the peripheral neuropathy, our data show that vestibular impairment is an additional challenge to balance that some CIDP patients will face.

Pediatric Multiple Sclerosis and Cognition: A Review of Clinical, Neuropsychologic, and Neuroradiologic Features.

Multiple sclerosis (MS) is an inflammatory demyelinating and neurodegenerative disease. Although cognitive impairment has been well established in adult patients with MS, its occurrence in patients with pediatric-onset MS has recently been reported. In this review, I discuss the main features of cognitive impairment in pediatric MS as determined by long-term follow-up studies, neuropsychiatric test batteries, and the results of neuroradiological imaging studies that investigated the pathogenesis of pediatric MS. The most commonly affected cognitive domains in adults are attention, processing speed, and visuomotor skills; language and intelligence are also affected in pediatric MS. A young age at disease onset is the strongest risk factor for these impairments, which may be due to the effect of inflammatory demyelination and neurodegeneration on the developing central nervous system and neural networks in children. Cognitive impairment has long-term effects on patients' academic life and the quality of their social life. Therefore, all patients with pediatric MS should be screened and monitored for cognitive impairment. This review also highlights the need for neuropsychological test batteries that assess different cognitive domains in children and adolescents with multiple sclerosis and for cognitive rehabilitation programs to improve the quality of their academic and social life.

Myasthenia gravis and thymoma coexisting with myotonic dystrophy type 1.

We describe a 34-year old man presenting with subacute generalized myasthenic symptoms. His clinical features and laboratory investigations demonstrated both myasthenia gravis and myotonic dystrophy type 1. The computerized tomography of chest revealed anterior mediastinal mass. The lymphocyte-rich thymoma was removed surgically and he received radiotherapy. Recent observations suggested that the patients with myotonic dystrophy may have an increased risk of benign and malignant tumours but its coexistence with thymoma is very rare. The risk of thymoma associated with myotonic dystrophy is unknown.

Assessment of early cognitive impairment in patients with clinically isolated syndromes and multiple sclerosis.

Objective. The aim of our study was to investigate the frequency and pattern of cognitive impairment in patients with clinically isolated syndromes and definite diagnosis of multiple sclerosis within the last 2 years. Methods. We assessed the cognitive status of 46 patients aged 18-49 years with clinically isolated syndromes or definite diagnosis of multiple sclerosis who have onset of their symptoms within the last 2 years. Patients were matched with 40 healthy participants for age, sex, and educational level. Neuropsychological assessment was performed by stroop test, paced auditory serial addition test (PASAT), controlled oral word association test (COWAT), clock drawing test, trail making test (TMT), faces symbol test (FST). Hamilton Depression Scale and Modified Fatigue Impact Scale were used to quantify the severity of any depression and fatigue the subjects might suffer. Results. 19.6% of early MS/CIS group failed at 4 and more tests and had significant cognitive impairment focused on attention, executive functions, memory, and learning. No significant relationship was found between cognitive impairment and disability and fatigue scores. Discussion. Cognitive impairment can be present from the earliest stage of multiple sclerosis. It should be considered among the main manifestations of MS even in the earliest stages of the disease.

Quality of life in patients with multiple sclerosis and urinary disorders: reliability and validity of Turkish-language version of Incontinence Quality of Life Scale.

Incontinence is one of the most frequently encountered problems in multiple sclerosis (MS), and it has a negative effect on the daily lives of patients. Therefore, it is important to investigate this complaint and start appropriate treatment early. The aim of our study was to demonstrate the validity and reliability of the Turkish-language Incontinence Quality of Life Scale (I-QOL) in patients with MS. We included 37 patients with MS in this study. For analysis of test-retest reliability, we administered the Turkish-language version of I-QOL developed by a "translation-back translation" method to patients on the day of admission and 1 week after admission. To assess validity, we also evaluated patients with the Multiple Sclerosis Quality of Life Scale (MQOL-54) and Expanded Disability Status Scale (EDSS). We calculated the intraclass correlation coefficient of the I-QOL (total and all subscores) as 0.88 to 0.91 and the Cronbach alpha score as 0.88 to 0.91 (p < 0.05). We found a significant correlation among all subscores of I-QOL and physical and mental subscores of MQOL-54 and EDSS (p < 0.05). Our study has demonstrated the internal consistency and reliability of the I-QOL in the Turkish language in patients with MS.

Atypical EEG findings in subacute sclerosing panencephalitis.

OBJECTIVE: To evaluate atypical electroencephalographic features in subacute sclerosing panencephalitis (SSPE) and to detect its relation to clinical features. METHODS: Twenty-two patients aged 2-17 years (mean 9.4 years) with definite diagnosis of SSPE were studied. Their clinical data and EEG records were reviewed retrospectively. All EEG records were analysed for features of periodic complexes (PCs) in relation to age, age at onset, clinical stage and the rate of progression as well as duration of the disease. RESULTS: Classical periodic complexes of SSPE were found in EEGs of 13 patients (group I). Atypical patterns were observed in EEGs of nine patients (group II). Two new atypical findings were identified: prolonged discharges which include sharp waves and slow waves for 4-7 s followed by suppression for 1-4s; and periodic complexes which consist of four or five sharp waves in every 2 s. We observed atypical EEG patterns were more frequently in Stage III, acute form, and the disease duration was longer than in the typical group. CONCLUSIONS: Atypical EEG patterns in SSPE might be related to the progression of the disease, but this theory needs further longitudinal studies. SIGNIFICANCE: We suggest atypical EEG patterns might be observed more frequently in patients with severe neurologic disability, more rapidly progressive disease and longer duration of disease.
